In general - there are no special gifts in Zimbabwe.
Regular souvenirs are sold mainly in the gift shops at the hotels.
Prices in these stores are very high, and he souvenirs should rather be called "African" and not Zimbabwean.
Here you can find all kinds of stylized masks, little things made of animal bones, feathers or skins - key chains, belts, necklaces, hair clips, pens, etc., as well as pillow cases and clothes embroidered with African patterns.
But still - What is it that you can bring that would be typical of Zimbabwe?
First of all - stone statues. To buy them you need to consult with local residents. Usually stone carvers are working in the middle of the field - you should know the place in order to be able to find them. One such place is just off the road near the airport in Harare.
Local craftsmen sculpt everything. From birds and small animals to monsters and fairy statues of human figures. Dimensions of these works also differ - from a few inches to five feet in height.
All made from natural stone. It looks good. But this still needs to be brought back home. So do not forget about the weight limits on the plane.
When buying feel free to bargain!
You can still visit a large supermarket. There's a good chance of finding biltong (Dried meat). Be sure to check the packaging and shelf life. Health standards in Zimbabwe are far from European standards.
